Medical and nursing students entering their clinical programmes are at increased risk for tuberculosis (TB) in TB-endemic settings. Relatively little is known about Mycobacterium tuberculosis infection among such students in high-endemic countries.

We examined M. tuberculosis infection among medical and nursing students starting clinical training in Bandung, Indonesia using interferon-γ release assay (IGRA) QuantiFERON-TB Gold Plus. IGRA-negative students had a repeat test after 1y and logistic regression was used to identify factors associated with IGRA positivity or conversion.

There were 379 students included in this study 248 (65.4%) were medical students and 131 (34.6%) were nursing students. Of 379 students, 70 (18.5%) were IGRA positive at baseline. Of 293 IGRA-negative students with 1-y results, 26 (8.9%) underwent IGRA conversion. Being a medical student (adjusted relative risk [ARR] 5.15 [95% confidence interval CI 1.82 to 14.59], p=0.002) and participation in sputum collection or bronchoscopy were associated with IGRA conversion (ARR 2.74 [95% CI 1.29 to 5.79], p=0.008).

Medical and nursing students entering clinical training are at high risk of M. tuberculosis infection and need improved infection prevention and control strategies.

These CHO mutants (51D1 and xrs6) are genetically deficient in one of the two important DNA repair pathways after genotoxic injury [homologous recombination (HR) and non-homologous end binding (NHEJ) pathways, respectively]. The contribution of indirect action on cell killing can be estimated by applying the maximum level of dimethylsulfoxide (DMSO) to get rid of OH radicals. To control the proportion of direct and indirect actions in lethal damage, we irradiated CHO mutant cells under aerobic and anoxic conditions. The contributions of indirect action on HR-defective 51D1 cells were 76% and 57% under aerobic and anoxic conditions, respectively. Interestingly, these percentages were similar to those of the wild-type cells even if the radiosensitivity was different. However, the contributions of indirect action to cell killing on NHEJ-defective xrs6 cells were 52% and 33% under aerobic and anoxic conditions, respectively. Cell killing by indirect action was significantly affected by the oxygen concentration and the DSB repair pathways but was not correlated with radiosensitivity. These results suggest that the lethal damage induced by direct action is mostly repaired by NHEJ repair pathway since killing of NHEJ-defective cells has significantly higher contribution by the direct action. In other words, the HR repair pathway may not effectively repair the DSB by direct action in place of the NHEJ repair pathway. We conclude that the type of DSB produced by direct action is different from that of DSB induced by indirect action.Contemporary cardiovascular medicine is complex, dynamic, and interactive. Therefore, multidisciplinary dialogue between different specialists is required to deliver optimal and patient-centred care. This has led to the concept of explicit collaborations of different specialists caring for patients with complex cardiovascular diseases-that is 'heart teams'. These teams are particularly valuable to minimize referral bias and improve guideline adherence as so to be responsive to patient preferences, needs, and values but may be challenging to coordinate, especially in the acute setting. This position paper-jointly developed by four cardiovascular associations-is intended to provide conceptual and practical considerations for the composition, structure, and function of multidisciplinary teams. It focuses on patients with complex coronary artery diseases in both elective and urgent setting and provide guidance on how to implement the heart team both in chronic and in acute coronary syndromes patients, including cases with mechanical complications and haemodynamic instability; it also discuss strategies for clear and transparent patient communication and provision of a patient-centric approach.

More patients survive myocardial infarction (MI) with cardiogenic shock (CS), but long-term outcome data are sparse. We aimed to examine rates of heart failure hospitalization and mortality in MI hospital survivors.

First-time MI patients with and without CS alive until discharge were identified using Danish nationwide registries between 2005 and 2017. One-, 5-, and 1- to 5-year rates of heart failure hospitalization and mortality were compared using landmark cumulative incidence curves and Cox regression models. We identified 85 865 MI patients of whom 2865 had CS (3%). Cardiogenic shock patients were of similar age as patients without CS (median age years 68 vs. 67), and more were men (70% vs. 65%). Cardiogenic shock was associated with a higher 5-year rate of heart failure hospitalization compared with patients without CS [40% vs. 20%, adjusted hazard ratio (HR) 2.90 (95% confidence interval (CI) 2.67-3.12)]. The increased rate of heart failure hospitalization was evident after 1 year and in the 1- to 5-year landmark analysis among 1-year survivors. All-cause mortality was higher at 1 year among CS patients compared with patients without CS [18% vs. 8%, adjusted HR 3.23 (95% CI 2.95-3.54)]. However, beyond the first year, the mortality for CS was not markedly different compared with patients without CS [12% vs. 13%, adjusted HR 1.15 (95% CI 1.00-1.33)].

Among MI hospital survivors, CS was associated with a markedly higher rate of heart failure hospitalization and 1-year mortality compared with patients without CS. However, among 1-year survivors, the remaining 5-year mortality was similar for MI patients with and without CS.
